I can't comment on your problem with VisualItemModel, but an alternative way
to approach your requirement (if I understood it correctly) would be
to use a Loader
to implement factory pattern. Something like this:
ListView {
model: dataModel
delegate: Loader {
source: if (itemType == 0) "BookDelegate.qml"
else if (itemType == 1) "SongDelegate.qml"
else "MovieDelegate.qml"
}
}
ListModel {
id: dataModel
ListElement {
itemType: 0
author: "William Shakespeare"
title: "There's something wrong in the land of Denmark"
pageCount: 654
}
ListElement {
itemType: 1
performer: "Michael Jackson"
album: "Thriller"
songTitle: "Beat it"
}
ListElement {
itemType: 2
movieTitle: "Raiders of the Lost Ark"
director: "Steven Spielberg"
}
}
I doubt using the Loader to choose the delegate gives you too much
overhead unless the expression used to choose the delegate becomes
really complex.
cheers,
Juha
